Recalbox 6.0 is working fine for Odroid XU4 emmc boot., while 6.1.1 is not

Ok, got it. You are right!! Recalbox 6.0 is working fine for Odroid emmc boot., while 6.1.1 is not

Was woundering why Image of 6.0 is 293mb, while 6.1.1 is 430mb?!

Can someone provide download link to Recalbox 6.0 ?
Is there an archive available?

Do you have another solution than to try fresh installation? Cause it is not working for odroid. By now I had to switch back to recalbox18.07.13.
Thanks for any answers in advance.

please see, same for Odrodi XU4

Same thing here. Only black screen and fan is going crazy wile starting in 6.1. Never made it to the start screen or in the app.
Installation via Etcher on a fresh formated eMMC 16 GB (Fat32)
Deleted my perfect optimized 4.1 system for that...

Any suggestions? Othwise I have to switch back to 4.1 is there an image available?

#edit tried fresh formated eMMC 16 GB (NTFS) as well. Same bug - black screen only
